FTP to SFTP Gateway

I would like to know if it is possible to create an FTP to SFTP gateway somehow or if there are any projects or code that currently solve my issue.

Issue:

I need to provide SFTP access to an OpenVMS server, but can't seem to find a free opensource solution that supports SSHv.2. VMS supports FTP, but I need to send files over the internet and they contain PHI, so the files need to to be transfered HIPPA compliant.

I would like to have some sort of box on my internal network would allow insecure connection on the internal side, and then send the data securely to the external server.

Current Situation:

Currently I have an external hardened SFTP server we allow our clients to use to send files to use securely. I was thinking about using rsync over ssh to bring the data in to a server on the internal network so that my VMS servers could access the data clients sent to us. However the problem of getting data from my VMS servers to the SFTP server still remains.

Currently Rsync talks to an NT box on my internal network over ssh. Internal users can drop files in client outbox folders wich then get sync'd back up with the external SFTP server into the coresponding client directories. The problem is that the data transfer is a push pull. We pull data from the out box of the client adn drop it in the in box for our internal users. We send the out box on the internal side to the in box of the client's directory on the SFTP server.

Question:

Can anyone think of a better way to accomplish the following goals?

1. Allow my VMS servers to directly log into an SFTP server.
2. Allow internal windows users to drop files in NTFS secured direcories on network shared drives, and have those files be sent securely to the SFTP server.
3. Allow client to manage their FTP directories.
4. Ability to archive every file ever transfered.

Current Stance:

What I think I am going to do is mirror my SFTP server with ssh and rsync starting at the chrooted /home/ directory to an internal NT server. There I will have some scripting to archive files daily out to tape. I will then use rsync to send the previous day's archive file back out to each clients directory so they have at least 1 days worth of data if they should need to recover a file.

I am now left with two problems, how do I get my VMS servers to talk to the SFTP server directly, and how can I allow easy access to send files for internal windoze users?

I know this is extremely complex, but anyone in the IT healthcare industry should feel my pain. Thanks to everyone! Damn HIPPA...

After further though on this issue...

I think my best route is to find and attempt to install an SSH client on my VMS servers so they can access my SFTP server. I will worry about internal user transfers at a later time.

If anyone has any information or suggestions at all, please let me know... Thanks!

Just incase anyone needs or wants to know...

This is the link to a site that has information on how to create an FTP to SFTP bridge.

Very soon I will be posting my documentation on how to create a completely free HIPPA compliant SFTP server made completely with Linux!

Features include:

User Authentication
User Auditing
Data Integrity protection
Disaster Recovery
Backup Architecture Integration
Cross-Platform Support
Auto-Archiving of any and all transfered files.
Encrypted file transfers
User management
Automatic OS and cryptography updating
Scheduled maintenance
Data Redundancy and Mirroring
